Understanding Oral Cancer

Oral cancer affects the mouth including the tongue, floor of mouth, cheek lining (buccal mucosa), gums, hard palate, and lips. India ranks among the highest globally for oral cancer incidence — it is the number one cancer in Indian men, strongly linked to tobacco chewing, gutka, paan, and areca nut habits prevalent across the country.

Pre-cancerous conditions such as leukoplakia (white patches), erythroplakia (red patches), and oral submucous fibrosis (OSMF) can transform into cancer over time. Regular screening is essential for individuals with tobacco habits. When detected early, oral cancer has excellent cure rates with modern surgical techniques that preserve function and appearance.

Causes & Risk Factors

1
Smokeless tobacco

Gutka, khaini, zarda, and paan masala — the leading cause in India

2
Smoking

Bidi, cigarette, and hookah use significantly increase risk

3
Betel quid & areca nut

Chewing betel with or without tobacco is a major risk factor

4
Alcohol consumption

Multiplies risk when combined with tobacco use

5
Oral submucous fibrosis (OSMF)

Pre-cancerous condition caused by areca nut chewing

6
Leukoplakia & erythroplakia

White or red patches in the mouth with malignant potential

7
Sharp or broken teeth

Chronic irritation to the tongue or cheek lining

8
HPV infection

HPV-16 associated with some oral cancers

9
Poor oral hygiene

Chronic inflammation increases cancer susceptibility

10
Nutritional deficiencies

Iron and vitamin A deficiency may contribute to risk

11
Previous oral cancer

Field cancerization increases risk of second primary tumors

How Is Oral Cancer Diagnosed?

Early detection of oral cancer is critical for better outcomes. Diagnosis combines clinical examination with imaging and tissue analysis to determine the stage and plan treatment.

Visual and tactile examination

Systematic inspection and palpation of the oral cavity

Toluidine blue staining

Highlights suspicious mucosal areas for targeted biopsy

Incisional biopsy

Tissue sample from the suspicious lesion for histopathology

FNAC

Fine Needle Aspiration Cytology for neck lumps

CT scan

Evaluates bone invasion and tumor extent in the jaw

MRI

Assesses soft tissue extent and perineural spread

PET-CT

Staging scan to detect distant spread

OPG (Orthopantomogram)

Panoramic X-ray to assess jaw involvement

Dental evaluation

Pre-treatment dental assessment for treatment planning

Neck lump or swelling

Early diagnosis improves outcomes

Treatments

Oral Cancer Treatment Options

Transoral Robotic Surgery (TORS)

Minimally invasive robotic surgery for accessible oral cancers, avoiding external incisions and jaw-splitting. Provides magnified 3D vision for precise tumor removal while preserving healthy tissue. Faster recovery with better functional outcomes.

Laser Excision Surgery

Precise laser removal for early-stage oral cancers and pre-cancerous lesions like leukoplakia. Minimal bleeding, reduced post-operative pain, and excellent healing. Ideal for superficial tumors and field cancerization.

Composite Resection with Reconstruction

For advanced cancers involving bone, comprehensive removal of tumor with mandible segment followed by immediate microvascular free flap reconstruction. Restores jaw structure, enables dental rehabilitation, and maintains facial appearance.

Neck Dissection

Selective or comprehensive removal of lymph nodes in the neck when cancer has spread or is at high risk of spreading. Nerve-sparing techniques preserve shoulder function and minimize complications.

FAQs

Frequently Asked Questions

The main risk factors for oral cancer in India are tobacco use (smoking and chewing), betel nut/paan consumption, alcohol, and HPV infection. Oral submucous fibrosis from areca nut chewing significantly increases risk. Early detection through regular dental check-ups is crucial for people with these risk factors.

Yes, oral cancer is highly curable when detected early. Stage I and II oral cancers have cure rates exceeding 80-90% with appropriate treatment. Even advanced cancers can be treated effectively with surgery, reconstruction, and adjuvant therapy. Dr. Vidhyadharan's expertise in comprehensive treatment maximizes cure rates.

Functional outcomes depend on tumor size and location. With minimally invasive techniques (TORS, laser) for early cancers, most patients maintain normal speech and swallowing. For advanced cancers requiring reconstruction, Dr. Vidhyadharan's reconstructive expertise and post-operative rehabilitation help restore function. Most patients return to near-normal eating and understandable speech.

Transoral Robotic Surgery (TORS) offers magnified 3D vision and precise instrument control, allowing tumor removal through the mouth without external incisions or jaw-splitting. Benefits include shorter hospital stay (3-4 days vs 2 weeks), faster recovery, less pain, better swallowing outcomes, and no visible scars. Dr. Vidhyadharan was trained in TORS at Royal Adelaide Hospital, Australia.

Recovery varies by procedure. Minimally invasive surgery (TORS/laser): 1-2 weeks to resume normal diet and activities. Major resection with reconstruction: 2-4 weeks in hospital, 2-3 months for full recovery. Speech and swallowing therapy accelerates functional recovery. Dr. Vidhyadharan's team provides comprehensive rehabilitation support.

Adjuvant treatment depends on final pathology findings. Early-stage cancers with clear margins often need surgery alone. Advanced cancers or those with high-risk features (positive margins, lymph node involvement, nerve invasion) typically require post-operative radiation with or without chemotherapy. The tumor board recommends the optimal plan.

Many oral cancers can be treated without mandibulectomy (jaw removal). Dr. Vidhyadharan uses TORS and laser surgery for tumors not invading bone. When bone is minimally involved, marginal mandibulectomy preserves jaw continuity. Only tumors deeply invading bone require segmental resection with immediate reconstruction to restore jaw structure and function.

Success rates at specialized centers like THANC Hospital match international standards. Early oral cancer (Stage I-II): 80-90% five-year survival. Locally advanced cancer (Stage III-IV): 50-70% depending on specific factors. Dr. Vidhyadharan's fellowship training, advanced surgical techniques, and multidisciplinary approach optimize outcomes.

Cost depends on the type of surgery (minimally invasive vs reconstruction), hospital stay duration, and adjuvant treatment needs. THANC Hospital offers comprehensive oral cancer care with transparent pricing. Insurance coverage is available for cancer treatment. Detailed cost estimates are provided after consultation and staging workup.

White patches (leukoplakia) are pre-cancerous lesions that may transform to cancer in 5-15% of cases. Red patches (erythroplakia) have higher malignant potential. Any persistent mouth patch lasting more than 3 weeks needs evaluation. Dr. Vidhyadharan can assess the lesion, perform biopsy if needed, and treat with laser excision to prevent cancer development.

Oral submucous fibrosis (OSMF) from betel nut/areca chewing causes progressive mouth tightness and significantly increases oral cancer risk. Early OSMF can improve with cessation of habits and medical treatment. Advanced fibrosis requires surgical release. Regular surveillance is essential as OSMF patients have 7-13% lifetime cancer risk. Stopping the habit is most critical.

Follow-up schedule: Monthly for first year, every 2-3 months for second year, every 3-4 months for years 3-5, then annually. Each visit includes examination for recurrence, imaging as needed, and management of treatment side effects. Dental care and nutritional assessment are part of comprehensive follow-up.
